That means that the video settings of your computer does not match the monitor. you need to go into safe mode by pressing F8 while pc is rebooting then change the settings of your video through the control panel.

Dell inspiron 530 desktop won't boot, fan is running, no signal on monitor


It sounds like either your monitor or video card inside the computer is bad.

If the monitor is showing the "No Input Signal" message then the video card inside the computer is bad. The monitor is ok otherwise it would not be able to display the No Input Signal message.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.



Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

HP Pavilion Elite m9400f on button flashing, won't start up.


try and pull your add-on cards and reinstall them as well as your memory. make sure that the little switch on the PSU is set to 115v. The clicking sounds like the hard drive, but if you're not getting any error or picture then i don't think that's the case. blow the computer out with compress air, open up the pc and try and start it and make sure that all the fans are spinning.

Vsonic flat screen monitor need blink codes


hi do you mean you are asking for the blinking codes on your viewsonic pc monitor?. usually lcd monitor for pc has no blinking codes, if your monitor just only a blinking indicator and won't turn on, you must check first the source from your pc if their is a signal to turn on the monitor. if just blinking only then won't turn on you must check the power supply of the monitor usually the main cause is bulging capacitor. just replace it with the same value and rating thanks for consulting the fixya good luck.

Menu keep on blinking


Disconnect the monitor from the computer. Then turn on the monitor, if the menu keeps on blinking then that means the screen is starting to go bad and the monitor needs to be replaced.
You can also hook up the monitor to another computer. If the blinking stops then that means its an issue with the video card in your original computer.

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

When i turn the computer on, it turns on but the blue light just starts blinking and nothing appears on the monitor?


Could be a bad power supply in the computer. Most power supplies are pretty cheap these days. Open up the PC and see which version you need. Most lekely an ATX. Good Luck!
